could you please share with me arduino uno programming for calculating power factor........ input to the arduino will be current zero crossing and voltage zero crossing ( for this i use the zero crossing detector)....... both are square wave and have zero and one(e.g 5v). my load is three phase induction motor and i am working on single phase and control the rest of two with them.

i have problem for finding power factor from zero crossing circuit through arduino i have achieve the voltage and the current signal through zero crossing detector now the problem is to calculate the delay between these two signal and calculate power factor from them pleas help me in this programing

Hello.. I am new for arduino uno microcontroller. I am working on power factor correction of single phase inductive load. I need a code for power factor calculation, I am using zcd circuit for voltage and current.

Hello sir actually i am working on TCR(Thyristor controlled reactor) so that i am also using peak detector to sense 90 degree bcz in TCR SCR will conduct in 90 to 180 nd 270-360 interval. so my question is that can i use 2 ZCD and 1 peak detector with arduino uno microcontroller...??

Also in this case when my load will pure inductive at that time my current wave will be not pure sine wave so at that time zcd's result would be wrong..!!

Thanks for your suggetion. bt In my project i am getting both the value of Vrms and Irms by using voltage and current sensing circuits but what about True power..?? How can i find it..?? Can you give me some coding of it..?
